How to Learn Coding

I’d like to share a programming tip that I’ve used for years. A large part of programming involves googling for code snippets you need on Stack Overflow and other websites. (Shh. Don’t tell the nondevelopers. ????)

Coding AI is the New Literacy

Today we take it for granted that many people know how to read and write. Someday, I hope, it will be just as common that people know how to write code. Several hundred years ago, society didn’t view language literacy as a necessary skill.

Learning for Humans, Learning for Machines

I’ve been trying to teach my toddler the alphabet. Despite having some educational experience, when she mispronounces a vowel for the nth time, I can’t help but feel like I’m doing it wrong.

Making AI Fair, Accountable, and Reliable

I spoke last week at the National Intergovernmental Audit Forum, a meeting attended by U.S. federal, state, and local government auditors. (Apparently some of the organizers had taken AI for Everyone.)

The Power of Sleep

I received a copy of Why We Sleep: Unlocking the Power of Sleep and Dreams as a Christmas gift — back in the pre-Covid era — and finished it last weekend. This book by Matthew Walker, director of UC Berkeley’s sleep and neuroimaging lab, is a useful reminder of the importance of sleep...

Why We Need H1-B Visas

I was dismayed on Monday to read that the U.S. is suspending the H1-B visa program at least through the end of the year. This effort to discourage immigration can only bring distress to workers from other countries and harm to the U.S.
